Been thinking about getting into NFA for years now, obviously price is an issue.  Also worried about showing up on some list via background checks in this day and age of connectivity and being tagged as unemployable.  I know I am paranoid, but half the time I am right.  

Anyway, dealer I know has an AR-15 A2 conversion supposedly done by weapon specialties.  Didn't spend a lot of time checking it out, seems clean with low use.  Anyway, I know everyone is down on SP1 conversion but why?

This one is marked AR-15 A2 but seems to be a transitional model and is basically an SP1 lower, no reinforcements and no fence.  Anyway its priced at $11k.

How is this in the scheme of things?  My biggest concern is I want something durable and troublefree.    Hence I am looking at Colt.  The big hole pin/screw has been converted into a big hole push pin.

Down on them because of big-hole takedown pin and many if not most Sporter II's (all that I've seen, at any rate) used the slab-sided lowers, and often slick-sided uppers with A1 style sights, as well.  If the conversion was done well, it'll be a keeper and a shooter, but you'll still be messing with offset adapter pins for your uppers.

Can you find flat top Colt uppers with the big hole or modify them to fit?

IIRC, AR15-A2, even though it has "A2" in its model designation, did not have a mag fence. Later models had tear drop forward assist. They all had 1/7 barrel and A2 rear sights.

Personally, if I had one, I would send it to M60 Joe and have him add bushings to bring the front holes to "spec". Or if you wont want a permanent modification, there are removable bushings.

For another $1,000 to $1,500, you can get a factory selective-fire Colt AR-15 Model 614, which is an M-16 rifle with export/law enforcement markings.  That would get you a standard Colt M-16A1 lower receiver (other than lacking the "M-16" marking on the magazine well, that's the ONLY difference), complete with factory "safe-semi-auto" markings and magazine fence.  These rifles also use the standard M-16 style captive front push pin of .250" diameter, allowing you to use any and all M-16 upper receivers.  They are the "bargain" of the factory full-auto Colts.
